   Object Linking and Embedding
   OLE
      <operating system> (OLE) A distributed object system and
      protocol from Microsoft, also used on the Acorn
      Archimedes.  OLE allows an editor to "farm out" part of a
      document to another editor and then reimport it.  For example,
      a desk-top publishing system might send some text to a word
    processor or a picture to a bitmap editor using OLE.
